びこの方法を実施する装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides anaerobic treatment of wastewater containing organic impurities by conducting the wastewater through at least one reactor and allowing anaerobic microorganisms to colonize a support material within the reactor. The present invention relates to a biological purification method and an apparatus for carrying out this method.

せる程過剰に支持材料上で繁殖する危険がある。 Such wastewater purification methods using anaerobic organisms have been known for a long time. A support material, usually consisting of rock, slag or activated carbon, prevents anaerobic microorganisms from leaving the reactor along with the treated wastewater and prevents as much as possible between the treated wastewater and the biomass or living organisms within the reactor. It helps to make good contact. However, such a method suffers from the drawback that the wastewater forms easy-to-flow channels within the reactor, so that only a small portion of the surface area of the support material is in contact with the wastewater. Furthermore, the gradual movement of the support material pieces, which would enhance the material conversion or exchange, cannot be easily carried out due to the nature of the material and would result in high wear on the support material itself. Furthermore, when using reactors with relatively large length-to-diameter channels and therefore only flow paths with low back-mixing, the growth of anaerobic bacteria is particularly important when the concentration of the organic substrate is high. There is a risk that growth will be hindered or destroyed. However, even if the loading of the supporting material with the organic substratum is not so great that the life forms are damaged, the life forms will not be affected if the laminar flow of the treated wastewater through the reactor is small. There is a risk of overgrowth on the support material to the extent that it can clog the reactor.
本発明の目的は、冒頭に述べた方法及びこの方

交換が強化されることが出来る。 By arranging a macroporous material with a low specific gravity as a support material, it is possible to increase the active surface area on which the very slowly growing microorganisms involved in the anaerobic treatment process can colonize. The microorganisms are uniformly fixed and distributed. This ensures that there is no loss of bacteria that would degrade the reactor's capacity or, in extreme cases, cause it to become clogged. In this case, the macroscopic pores of the support material force the bacteria to grow in a dispersed manner, which provides an essentially larger surface area for mass exchange than in conventional methods with different support materials and allows for excessive growth. is inherently prevented.
Furthermore, due to the low specific gravity of the macroporous material, if the macroporous material is made up of individual pieces of material, a sufficient turbulence can be generated even at a low flow rate of the wastewater to be treated; Thus, material exchange can be enhanced.
交換表面が大きいこと及びこれによつて得られ

うな短い処理時間となすことが出来る。 Owing to the large exchange surface and the resulting large cleaning effect, the method according to the invention allows for a final
In order to purify the wastewater as much as possible to a BOD 5 or BSB 5 content, there is no need for further wastewater treatment, and the downtime is relatively short. However, the process according to the invention can be implemented particularly economically as a prepurification step for a downstream final purification stage, in which case a prepurification final BSB 5 value of approximately 100 mg/C is obtained. There must be. The large mass exchange area allows for short treatment times, such as days or hours.

出来る。 If the anaerobic biological decomposition process is carried out in two reactors, the acid phase formation takes place in the first reactor and the methane phase formation takes place in the second reactor. In this case both reactors or only the second reactor can be provided with the support material according to the invention.

も支持材料片の渦流が容易に得られるのである。 It is suitable for this purpose to use as supporting material substances with a specific gravity of 10 to 200 kg/m 3 and open macropores with a diameter of 0.1 to 5 mm.
This large size of the macroscopic pores provides a large surface area for colonization of bacteria involved in the anaerobic biological treatment process and significantly prevents pore clogging. Furthermore, due to the low specific gravity, swirling of the supporting material pieces can be easily achieved even at low flow rates of the waste water being treated.

えることが出来る。 It is advantageous to use substances consisting of organic polymeric compounds as support materials which meet the above-mentioned conditions. Polyurethane foams, polyurethane foam rubber or similar materials known in the synthetic material industry, especially with open macropores, meet the above requirements and to which are added cost-advantageous scrap material. I can do it.

うな大きさの材料片は既述のように物質交換を更
に強化する為に容易に渦流を生じ得る。 In a preferred embodiment of the method of the invention, individual pieces of material with a diameter of 10 to 50 mm are used as support material. This size of the individual pieces of material allows for large concentrations of organisms. Furthermore, pieces of material of such size can easily create swirling currents to further enhance mass exchange, as described above.
このような理由で、支持材料によつて渦流床を
形成し、廃水を下方から上方に向つて反応装置を
通して適当な速度で導くのが特に有利である。 For this reason, it is particularly advantageous to form a swirled bed with the support material and to conduct the waste water from the bottom upwards through the reactor at a suitable velocity.

材料の棒から作られることが出来る。 It is advantageous for the same purpose to operate the reactor as a stirred reactor. Approximately 1 to 10 of the stirring device
At gradual rotational speeds of revolutions per minute, the mechanical stresses occurring in the pieces of supporting material are so small that they do not fracture. On the other hand, this rotational speed is sufficient to move the individual pieces of material so that a strong mass exchange is possible. The stirring device can be made, for example, from a simple rod of flexible synthetic material.

なことを充分に阻止する。 However, when treating wastewater with high impurity,
It is suitable for this purpose to form a fixed bed with the supporting material in order to obtain a sufficient mass exchange action. Particularly when using individual pieces of material as support material, the flow rate of the waste water must be adjusted accordingly. However, instead of using individual pieces of material, it is also possible to provide a single large mass of organic polymeric compound within the reactor. The cellular structure of such a mass sufficiently prevents the bacteria involved in the anaerobic treatment process from growing in thick layers and clogging the reactor.
